WCNN'93, Portland: World Congress on Neural Networks, July ...
the fly's lamina (Ogmen and Gagne', 1990). However, unlike an on-off unit which
only signals the onset and offset of an input stimulus, our ommatidial node
uniquely identifies the stimulus as an increase or decrease from the delayed
stimulus.

A Phenotypic and Genetic Characterization of the Cell ...
The complete mechanism underlying ommatidial rotation remains unclear.
Manipulation of cell-cell adhesion and response to cell signaling are clearly vital
for correct ommatidial rotation, but the means by which ommatidia coordinate
these ...
Jennifer Lynn Fetting, 2009

A Morphological and Genetic Analysis of Directed Cell ...
This observation led to the hypotheses that ommatidial rotation occurs in two 45°
steps, that these steps can be genetically separated, and that nmo is essential for
the second step (from 45° to 90°) (Choi and Benzer 1994; Brown and Freeman ...

Cascade of photoreceptor determination in a developing ommatidial cluster. R8,
the first cell to be determined, expresses atonal (ato) and signals neighboring
cells to ...

Fundamental Neuroscience
As they leave the MF, cells of the eye disc become arranged in a pattern of “
rosettes”that foreshadow the regular ommatidial pattern. Soon afterward, one cell
is singled out in each rosette to become R8. Being the first cells to differentiate,
R8 ...

The Nemo Kinase Regulates
Ommatidial Rotation in the ...
However, the mechanisms of rotation are not understood. Results of this work suggest that Nemo kinase regulates rate of rotation by specifically acting on cadherin-catenin complexes at the level of adherens junctions.

Determinants of Neuronal Identity
How can discrete, evenly spaced ommatidial units arise from an apparently
homogeneous epithelial sheet? In grasshoppers, elegant ablation experiments
have provided one possible answer (Doe and Goodman, 1985). Neuroblasts in
the ...
In the eyes of Papilio (Fig. 7.3) and Pieris, the situation is more complicated. In
these eyes, even the long-wavelength receptors (i.e. short visual fibres) differ in
sensitivity between the ommatidial types. The expression of different opsin genes
...

“A prominent feature of Drosophila eye development is the 90 degrees rotational
movement of the multicellular ommatidial precursors within a matrix of stationary
cells. We demonstrate that the cell adhesion molecules Echinoid (Ed) and ...
